摘要: Abstract This work investigates the microstructure, optical absorption, electrical resistivity and LPG (Liquefied Petroleum Gas) response of ZnO thin film with change in relative doping concentrations In Fe host lattice. All films retain polycrystalline nature hexagonal wurtzite unit cell structure. Scanning electron microscopic study reveals that regular spherical shaped nanoparticles are formed undoped ZnO, but a compact surface morphology has obtained case 3 at.% doped (IZO) owing to reduction particle size. 1 at.% co-doping IZO, nano-flakes formed. However, at higher concentration, this typical gradually changes shapes again. By comparing energy dispersive X-ray analysis data, formation flakes type nanostructures is attributed presence excess oxygen sample it dominates thermally activated conductivity phenomenon low temperature range. Fe-In results transmittance band gap ZnO. It also lowers IZO film. samples exhibit better than co-doped its smaller
